ARM: tegra: adapt to latest HSP DT bindingThe DT binding for the Tegra186 HSP module apparently wasn't quite finalwhen I posted initial U-Boot support for it. Add the final DT binding docand adapt all code and DT files to match it.Signed-off-by: Stephen Warren <swarren@nvidia.com>Reviewed-by: Simon Glass <sjg@chromium.org>Signed-off-by: Tom Warren <twarren@nvidia.com>

Add a mailbox driver framework/uclassA mailbox is a hardware mechanism for transferring small message and/ornotifications between the CPU on which U-Boot runs and some other devicesuch as an auxilliary CPU running firmware or a hardware module.This patch defines a standard API that connects mailbox clients to mailboxproviders (drivers). Initially, DT is the only supported method forconnecting the two.The DT binding specification (mailbox.txt) was taken from Linux kernelv4.5's Documentation/devicetree/bindings/mailbox/mailbox.txt.Signed-off-by: Stephen Warren <swarren@nvidia.com>Acked-by: Simon Glass <sjg@chromium.org>
